Description

Technical Field

[0001] The utility model relates to the field of sowing equipment, in particular to a two-way driving device of a sowing machine based on a soil sealing roller. Background Art

[0002] With the continuous advancement of agricultural machinery technology, small-seed crops such as sesame are now gradually being mechanized using seed drills. These machines are multifunctional, integrating functions such as fertilization, sowing, furrowing, and soil covering, and can perform fertilization and sowing operations simultaneously. However, due to the small size of sesame seeds, their poor soil-lifting ability, and irregular grain shape, high sowing quality requirements are required. Utility model patent publication number CN219182045U discloses a sesame sowing soil-covering roller drive device. During the forward rolling operation of the soil-covering roller of the device, the sprocket and chain are linked to drive the fertilization mechanism and the sowing mechanism to operate synchronously. No special traction device is required to provide power, which is beneficial for energy saving and cost reduction. However, during the operation, splashed soil or stalks often get stuck in the chain and sprocket, requiring frequent cleaning. In addition, the chain drive is prone to tension loss, which affects the transmission effect and requires frequent maintenance to ensure tension. This is a problem that needs to be improved.

[0020] A triangular seat 133 is provided on the side of the right-angle diverter A 131 and the right-angle diverter B 132, and a triangular seat 133 is correspondingly provided on the bracket at the end of the sealing roller 13. The two triangular seats 133 are fixed by bolts. The triangular seat 133 can increase the contact area between the right-angle diverter and the bracket, and improve the stability of its installation on the bracket.

[0021] Example 2, see Appendix 3-7, this example is basically the same as Example 1, except that: the connecting rod A 14 includes a polygonal shaft 141 and a polygonal sleeve 142, the outer end of the polygonal shaft 141 is connected to the output shaft of the right-angle steering gear A 131, and the outer end of the polygonal sleeve 142 is connected to the input shaft of the stepless speed reducer 113, and the polygonal shaft and the polygonal sleeve serve as the transmission shaft between the stepless speed reducer 113 and the right-angle steering gear A 131. 42 are slidably sleeved between the inner ends, and the structure and connection method of the connecting rod B 15 are the same as those of the connecting rod A 14.
